Garden help

Question

Hi,

I have spent more money than I can count on my garden. We have issues keeping plants and bushes alive. I have called numerous landscapers out and they all have varying opinions. We had a very well known group come out and she was sure it was a fungus. So we got on the yearly maintenance program and she assures us it would all get better but it has not. We have boxwoods that just randomly die. Rose bushes that die and other larger plants whose leaves turn brown
And begin to die.

We are in a drought here and my current watering schedule is 3 days a week 25 min a day. I ramped it up to 5 days a week and that didn’t seem to help. It only made the boxwoods die more quickly.

What should I do?

Answer 1

These articles should help. They do look like fungal issues. I would cut back on the watering and make sure your plants have plenty of air circulation. It looks like the plants are very close together, but it may just be the photo angle. I would also suggest a soil sample, if you have not done that yet. Could be something amiss in the soil. I also wondered about nematodes, that nibble on plant roots and cause their demise. They are addressed in the boxwood article.
